This invention relates to auxiliary lighting, and more particularly, to an auxiliary puck light with a pivoting head.
Auxiliary lighting takes on many functionalities in the modern world. Lighting is needed in spaces that require visibility, such as closets, cabinets, under cabinets, tents, automobiles etc. In the working environment, a worker usually requires light in the region that he/she has to work. Either a separate person is employed to hold and direct the light or the light is hung in place. The hung light may swing or become unstable. If the light is fixed in place to avoid instability, the light is usually difficult to adjust or rotate. Changing the illuminating direction and/or region of the light is difficult. In addition, fixed lights restrict the applicable range of the light and transportation of the lighting source.
The above lights generally utilize fluorescent or incandescent lamps as a light source. Fluorescent and incandescent lamps typically require filaments and cathode tubes for operation. As such, they are fragile and have a relatively short operating life. Furthermore, filament lamps are not the most economical to operate. In addition, by producing light by heating a filament, incandescent lamps generate a great deal of heat. This heat build up limits the effectiveness of traditional auxiliary lighting due to safety considerations and the possibility of unintentionally and adversely heating items in the near vicinity. This heat generation also makes traditional puck lights less versatile in that some places in which such a light would be desired cannot accommodate a large buildup of heat (e.g. closets, shelves, etc.). Moreover, traditional incandescent and fluorescent lights are quite inefficient. Incandescent lights convert a large amount of energy to heat rather than light, and fluorescent lamps have a relatively high start up power consumption.
Light Emitting Diodes (LEDs) are solid-state semi-conductor devices that convert electrical energy into light. LEDs are made from a combination of semi-conductors and generate light when current flows across the junctions of these materials. The color of the light produced by the LED is determined by the combination of materials used in its manufacture. LEDs have made significant advances in providing a higher performing light source since their inception. For example, red-emitting AlGaAs (aluminum gallium arsenide) LEDs have been developed with efficacies greater than 20 lumens per electrical watt, such devices being more energy efficient and longer lasting producers of red light than red-filtered incandescent bulbs. More recently, AlGaInP (aluminum gallium indium phosphide) and InGaN (indium gallium nitride) LED's have succeeded AlGaAs as the brightest available LEDs. As a result, LEDs have become cost effective replacements for standard incandescent light sources in various applications, such as automotive brake lights, roadway work zone safety lights and red stoplights. It would be advantageous to provide an LED light source for auxiliary lighting, which replaces the traditional filament or fluorescent lamp with an LED light source.
The primary object of the present disclosure is the creation of a rotating LED light on a magnetic base.
A further object of the present disclosure is the creation of an illumination system that includes an LED module or housing and a mounting base. A plurality of LEDs are mounted on the housing to serve as a light source and generates a light pattern. The housing can be easily rotated about the base unit to provide a rotatable mounting architecture. A battery system provides power to the LEDs.
A detailed description of preferred embodiments of the present invention follows, with reference to the attached drawings, wherein:
This disclosure is drawn to a puck shaped LED light with a rotating magnetic base.
The auxiliary light of the present invention may be made from any materials that are well known within the art. For instance, the base 30 may be composed of acrylonitrile butadiene styrene (ABS) plastic resin, the magnetic base 10 may be composed of a sturdy rubber or plastic material, the housings 80 and 70 may be composed of color anodized aluminum, ABS, mixtures thereof or the like and the post 50 may be composed of nylon resin, such as PA6+30% GF, steel alloy, such as carbon steel, mixtures thereof or the like.
On/Off switch 82 contacts batteries located inside housing 80 in order to activate the electrical connection supplied to LED lights arranged at the top of housing 80. See
Top 90 includes tubular screw attachments 96.
In addition, the auxiliary light of the present invention may also contain an AC power adapter/recharger for providing AC power to the LEDs and for recharging the DC power source. In addition, the power may be regulated with a switch that can control the level of intensity output of the LEDs.
It is to be appreciated that the various components of the present invention may be connected by any means that is well known within the mechanical arts. The multiple components of the present invention may be threadedly attached, screw attached, glue attached, lock joint with snap ring attached, snapped together, mixtures thereof and the like.
The assembly of the present disclosure may be implemented in other possible applications. The final characteristics of the lighting assembly may be applied to any application that may benefit from the novel properties of the present disclosure. For example, the lighting housing maybe any shape, design or size that may be reasonably associated with the novel rotational mounting. In addition, the LEDs may be incorporated to exhibit any color arrangement as desired for any particular purpose.
It is to be understood that the present disclosure is not limited to the illustrations described and shown herein, which are deemed to be merely illustrative of the best modes of carrying out the invention, and which are susceptible of modification of form, size, arrangement of parts and details of operation. The present disclosure rather is intended to encompass all such modifications which are within its spirit and scope as illustrated by the figures and defined by the claims.
